Abstract

Tests were conducted to determine if correlation could be obtained between tire wear rates experienced on automobiles and accelerated wear rates generated on towed trailers with the wheels set at a side slip angle. Fair correlation was obtained between car experience and that with trailers with free rolling wheels set at equal slip angle; better correlation was obtained between car experience and that with trailers with free rolling wheels set at the appropriate slip angle so that all tires generated the same cornering force; this level of correlation, however, was not deemed enough to be useful as a tire wear rating system.
